Q & A
Q: 請問 debug 過程參考哪些 Rpi 的手冊？
A: 參考的手冊有 BCM2711 ARM Peripherals、Arm Architecture Reference Manual Armv8, for Armv8-A architecture profile 以及 ARM Cortex-A Series Programmer's Guide for ARMv8-A
Q: AMT有導入 device tree 機制嗎？或是就是有其他設定方式描述例如記憶體位置 …？
A: 目前沒有，原因是目前樹莓派上的實作還沒有 SD card 的驅動可以使用，所以沒辦法在 runtime 取得 dtb。
Q: 請問您在找那些硬體部分的問題是怎麼找的，像是rpi3和rpi4的emmc0的部分？
A: 主要是在社群上發問找答案，樹莓派論壇上有許多大佬持續在研究這些議題。
關於 emmc0 的討論可以參考 => Read/write SD card on Raspberry Pi 4?
